perfect, just what I need, I even have 6mm steel balls for it SUPER.
oeps forgot, thank you very much :-)

Thanks for your comment!

What size balls do u use?

6mm Softair balls

Just did mind me selling my remix ?

No, it is your remix.

what size bearing is this can u make it 608?

This bearing is close to a 6001 (12 x 28 x 8) or 16001 bearing (12 x 28 x 7).
Its dimensions are 10 x 28 x 7.5.

Feel free to take my design and model it to any size you want.

I made a remix to a 608 beating mind me selling it for spinners it also holds mettle balls

Congrats, you set a new standard in personal 3D printed ball bearing quality.
What about a printable raceway grinder and polisher. possible / beneficial ?

Thanks for your comment!

I do not think that it is necessary to polish the raceway. The balls are running in the same directions as the layers are printed, that means the friction is quite low.

I print this bearing with a layer hight of 0.08 or even 0.05mm. I can hardly feel the layers. Therefore I am more concerned about the plastic balls. They have some nasty burrs and need to be cleaned.

I used G&G Bio-BBs 0.20g 5.95 +/-0.01mm diameter and it works perfectly. "The same manufacturing process as the precise steel ball bearing"

I just ordered some steel BBs. Let's see how good they work.

I was concerned about the layer change positions but you probably spread them out and with your layer they almost vanish.
Sad news that those balls are of such poor quality.

Great!

  1. Is there a reason why you uploaded nner_c_2.stl and cage.stl "upside down"? I used Pleasant3D (OS X) to invert them.

  2. Which Slicer did you use? (I generally use slic3r)
  1. I design the parts in assembly position. When I export them to STL they can be upside down or even sideways.

  2. I am using Cura. Cura let's me position, rotate and flip the parts before slicing.

Nice!

IIRC, 'real' (steel) bearing are made without any forcing or anything to put the balls in, removing the cage allows the balls to all fit in on one side.

It should therefore be possible to make a caged bearing with a monolithic inner race.
